dr Joanna Maria Rojek

Area of research: fertilization-independent development in sexual plants; the embryological processes, ranging from sporogenesis, gametophytes development, mechanism of fertilization, until the embryo and endosperm development; mechanisms of sexual or apomictic reproduction within Brassicaceae and Orchidaceae. Impact of unstable /stressful environmental conditions on plant reproduction.
